When the thoughts of a man that has a design in hand, running over a multitude of things, observes how they conduce to that design, or what design they may conduce unto; if his observations be such as are not easy, or usual, this wit of his is called prudence, and dependeth on much experience, and memory of the like things and their consequences heretofore. In which there is not so much difference of men as there is in their fancies and judgements; because the experience of men equal in age is not much unequal as to the quantity, but lies in different occasions, every one having his private designs. To govern well a family and a kingdom are not different degrees of prudence, but different sorts of business; no more than to draw a picture in little, or as great or greater than the life, are different degrees of art. A plain husbandman is more prudent in affairs of his own house than a Privy Counsellor in the affairs of another man.
To prudence, if you add the use of unjust or dishonest means, such as usually are prompted to men by fear or want, you have that crooked wisdom which is called craft; which is a sign of pusillanimity. For magnanimity is contempt of unjust or dishonest helps. And that which the Latins call versutia (translated into English, shifting), and is a putting off of a present danger or incommodity by engaging into a greater, as when a man robs one to pay another, is but a shorter-sighted craft; called versutia, from versura, which signifies taking money at usury for the present payment of interest.
As for acquired wit (I mean acquired by method and instruction), there is none but reason; which is grounded on the right use of speech, and produceth the sciences. But of reason and science, I have already spoken in the fifth and sixth chapters.
The causes of this difference of wits are in the passions, and the difference of passions proceedeth partly from the different constitution of the body, and partly from different education. For if the difference proceeded from the temper of the brain, and the organs of sense, either exterior or interior, there would be no less difference of men in their sight, hearing, or other senses than in their fancies and discretions. It proceeds, therefore, from the passions; which are different, not only from the difference of men's complexions, but also from their difference of customs and education.
The passions that most of all cause the differences of wit are principally the more or less desire of power, of riches, of knowledge, and of honour. All which may be reduced to the first, that is, desire of power. For riches, knowledge and honour are but several sorts of power.
And therefore, a man who has no great passion for any of these things, but is as men term it indifferent; though he may be so far a good man as to be free from giving offence, yet he cannot possibly have either a great fancy or much judgement. For the thoughts are to the desires as scouts and spies to range abroad and find the way to the things desired, all steadiness of the mind's motion, and all quickness of the same, proceeding from thence. For as to have no desire is to be dead; so to have weak passions is dullness; and to have passions indifferently for everything, giddiness and distraction; and to have stronger and more vehement passions for anything than is ordinarily seen in others is that which men call madness.
Whereof there be almost as may kinds as of the passions themselves. Sometimes the extraordinary and extravagant passion proceedeth from the evil constitution of the organs of the body, or harm done them; and sometimes the hurt, and indisposition of the organs, is caused by the vehemence or long continuance of the passion. But in both cases the madness is of one and the same nature.
The passion whose violence or continuance maketh madness is either great vainglory, which is commonly called pride and self-conceit, or great dejection of mind.
Pride subjecteth a man to anger, the excess whereof is the madness called rage, and fury. And thus it comes to pass that excessive desire of revenge, when it becomes habitual, hurteth the organs, and becomes rage: that excessive love, with jealousy, becomes also rage: excessive opinion of a man's own self, for divine inspiration, for wisdom, learning, form, and the like, becomes distraction and giddiness: the same, joined with envy, rage: vehement opinion of the truth of anything, contradicted by others, rage.
Dejection subjects a man to causeless fears, which is a madness commonly called melancholy apparent also in diverse manners: as in haunting of solitudes and graves; in superstitious behaviour; and in fearing some one, some another, particular thing. In sum, all passions that produce strange and unusual behaviour are called by the general name of madness. But of the several kinds of madness, he that would take the pains might enrol a legion. And if the excesses be madness, there is no doubt but the passions themselves, when they tend to evil, are degrees of the same.
For example, though the effect of folly, in them that are possessed of an opinion of being inspired, be not visible always in one man by any very extravagant action that proceedeth from such passion, yet when many of them conspire together, the rage of the whole multitude is visible enough. For what argument of madness can there be greater than to clamour, strike, and throw stones at our best friends? Yet this is somewhat less than such a multitude will do. For they will clamour, fight against, and destroy those by whom all their lifetime before they have been protected and secured from injury. And if this be madness in the multitude, it is the same in every particular man. For as in the midst of the sea, though a man perceive no sound of that part of the water next him, yet he is well assured that part contributes as much to the roaring of the sea as any other part of the same quantity: so also, though we perceive no great unquietness in one or two men, yet we may be well assured that their singular passions are parts of the seditious roaring of a troubled nation. And if there were nothing else that bewrayed their madness, yet that very arrogating such inspiration to themselves is argument enough. If some man in Bedlam should entertain you with sober discourse, and you desire in taking leave to know what he were that you might another time requite his civility, and he should tell you he were God the Father; I think you need expect no extravagant action for argument of his madness.
This opinion of inspiration, called commonly, private spirit, begins very often from some lucky finding of an error generally held by others; and not knowing, or not remembering, by what conduct of reason they came to so singular a truth, as they think it, though it be many times an untruth they light on, they presently admire themselves as being in the special grace of God Almighty, who hath revealed the same to them supernaturally by his Spirit.
Again, that madness is nothing else but too much appearing passion may be gathered out of the effects of wine, which are the same with those of the evil disposition of the organs. For the variety of behaviour in men that have drunk too much is the same with that of madmen: some of them raging, others loving, others laughing, all extravagantly, but according to their several domineering passions: for the effect of the wine does but remove dissimulation, and take from them the sight of the deformity of their passions. For, I believe, the most sober men, when they walk alone without care and employment of the mind, would be unwilling the vanity and extravagance of their thoughts at that time should be publicly seen, which is a confession that passions unguided are for the most part mere madness.
The opinions of the world, both in ancient and later ages, concerning the cause of madness have been two. Some, deriving them from the passions; some, from demons or spirits, either good or bad, which they thought might enter into a man, possess him, and move his organs in such strange and uncouth manner as madmen use to do. The former sort, therefore, called such men, madmen: but the latter called them sometimes demoniacs (that is, possessed with spirits); sometimes energumeni (that is, agitated or moved with spirits); and now in Italy they are called not only pazzi, madmen; but also spiritati, men possessed.
There was once a great conflux of people in Abdera, a city of the Greeks, at the acting of the tragedy of Andromeda, upon an extreme hot day: whereupon a great many of the spectators, falling into fevers, had this accident from the heat and from the tragedy together, that they did nothing but pronounce iambics, with the names of Perseus and Andromeda; which, together with the fever, was cured by the coming on of winter: and this madness was thought to proceed from the passion imprinted by the tragedy. Likewise there reigned a fit of madness
